Oh yeah...many times.
I remember in one congregation I was in way back, there was this one brother, he was employed by another brother (janitor work, surprising isn't it?).
This brother, I'll give him the name: Brother Bucktooth. The elder who ran the show: Brother Fair&Square.
Brother Fair&Square, was decent. As an elder, he was actually a pretty decent guy, and he was never negative towards me. But, he hired Brother Bucktooth, who was from a small community outside of the small city I lived in. He had a ton of kids, and the wife was perpetually knocked-up.
Brother Fair&Square hired a bunch of us Witnesses, and a couple who were not.
Because he was so busy, he had Brother Bucktooth, basically supervise us.
HE WAS A PRICK!
He always acted decent when Brother Fair&Square showed up. But Brother Bucktooth coming from the land of hay, piglets and outhouses, developed quite the chip on his shoulder. He was very authoritative. He was bossy, and like Jehovah...you could NEVER please him and he'd scream at you to clean 'such and such' again, because it was unsatisfactory.
Brother Bucktooth looked the guy from "Ernest Goes To Camp". We swear he could open pop-bottles with his teeth.
There are times where he riled me so badly I wanted to sock him. He was such a dick. But you know, that's not 'good Christain behaviour'. Someone, I think, one of the sisters finally had enough and went to Brother Fair&Square, and the Bucktoothed varmint, was the following week, moved to another cleaning location. (City Sewage Plant)
Years after being a JW, I had a few skirmishes. I don't like to go there, because honestly, it's not good for you. Besides, you never know who can get hurt or worse. Best to back away if you can, and if possible, avoid the situations period.
But yeah, there were a few I wish I could have pummelled with a rubber crutch.
Don't think I'm alone on that one.
